PRESS.

SPECIFICATION formingpart of Letters Patent No. 680,542, dated August13, 1901.

Application filed March 5, 1901.

To all whom, t may concern:

Be it known that I, JOHN S. PETER, a citizen of the United States, and aresident of Fort WVorth, in the county of Tarrant and State of Texas,have invented a new and Improved Press, of which the following is afull, clear, and exact description.

This invention relates to a press adapted particularly for forcingtie-plates into railway-ties.

This specification is a specific description of one form of theinvention, while the claim is a definition of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a-part ofthis specification, in which similar characters of reference indicatecorresponding parts in both views.

Figure l is a front elevation of the invention, and Fig. 2 is a sideelevation thereof.

The press comprises a yoke @,with a wide base a', which serves todistribute the pressure evenly on the tie and also to keep the press inupright position on the ground or other surface on which it may beplaced. The sides of the yoke a are extended upward in parallelism toform bearings a2, in which is mounted 4a shaft b. This shaft is held byCotter-pins b', and it carries a cam c, having a stud-like shank c. Thecam c has a steadilyincreasing radius somewhat in the form of a spiral,as shown. Arranged on the shaft at each side of the cam c and betweenthe bearings a2 are washers d, which keep the cam properly disposed onthe shaft b. The cam may be turned freely around its axis, as indicatedby dotted lines in Fig. 2, and for facili- Serial No. 49,760. (Nomodel.)

tating applying the necessary force to the cam a hand-lever (indicatedat e in Fig. 2) may be engaged with the shank c by means of a socket onthe hand-lever, as shown.

f represents the Wooden railway-tie, and g represents the tie-plate, theflanges of which are to be embedded in the tie f. Arranged between thetie-plate and cam is a block or stout plate h, which serves primarily tobear the pressure of the cam and uniformly to conlmunicate the same tothe tie-plate. By throwing the Vcam to the position indicated by dottedlines at the right of Fig. 2 the parts g' and h may easily be placed inposition, and then by moving the cam in the direction of the arrow tothe position shown by dotted lines at the left of Fig. 2 the action ofthe cam will force the Hanges of the tie-plate into the tie.

I-Iaving thus described my invention, I claim as new and desire tosecure by Letters Patent-- A tie-plate press, comprising a yoke havingbearings at its upper portion, a kshaft mounted in the bearings, and acam carried on the shaft and having a steadily-increasing radiussomewhat in the form of a spiral, the cam working with the yoke in themanner explained.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN S. PETER.
